Using CueCat USB barcode reader with Mac OS X

I got it from LibraryThing (also available from Amazon), to ease the task of entering books from my library into the database (presumably LT, but will consider using Delicious Library when it's 2.0 is available).

Unfortunately CueCat spits out encrypted data and needs a simple modification before it sends out any meaningful digits. I followed instruction at this site and it worked fine.

Note that you do not need this modification if you use it only on LibraryThing... it automatically decrypts the code for you.
